From another website to the same question -
"The programme was an hourly show called "Home At Eight". The first series, which was hosted by Richard Attenborough, began on 21 April 1952. The programme had a number of different segments, including "On Stage Please" featuring RADA students in their last year of study, "Off The Record" showcasing a recording artiste of the day, and "Thanks for the Melody" - hits of today and yesterday played by Peter Yorke and his Concert Orchestra.with the Ipswich Girls' Choir.
The part of the programme that you recalled was "Mrs Doom's Diary" - a macabre parody of "Mrs Dale's Diary". This, as you rightly say, starred Hermione Gingold and Alfred Marks.
Each week, Hermione Gingold served her witches brew to her doom laden husband (Alfred Marks) with the words:
"Tea, Edmond?"
"Yes Drusilla" came the reply
"Millock?"
The Doom's nasty son was played by Richard Attenborough whilst their butler Trog was heard only as heavy steps.
Jerry Desmonde took over as host of the second series of "Home at Eight" in September 1952 and was joined by the vocal group The Stargazers. "
